ABSTRACT OF THE DISCLOSURE A mixed basic metal sulfide catalyst having the formula: xA.yB.zC.qS wherein A is an alkali metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures, thereof, preferably lithium; B is selected from the group consisting of; a cation which has an ionization state 1 greater than the ionization state of C wherein B is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron, and mixtures thereof, preferably boron, aluminum yttrium, and lanthanum when C is selected from beryllium, magnesium, calcium, strontium, barium, radium, zinc, cadmium, mercury and mixtures thereof, preferably magnesium, calcium, barium and zinc; and B is selected from titanium, zirconium, hafnium, silicon and mixtures thereof, when C is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron and mixtures thereof, preferably boron, aluminum, yttrium, and lanthanum; and a cation which has an ionization state 2 and 3 greater than the ionization state of C wherein B is selected from hafnium, tantalum, niobium, vanadium and mixtures thereof, preferably tantalum; C is selected from magnesium, calcium, strontium, barium, and mixtures thereof, preferably magnesium; x and y are in the mole fractions of z such that when z=1 then x=0.001 to 0.25, preferably 0.05 to 0.15 and y=0.001 to 0.25, preferably 0.002 to 0.20; and IGT-1123-B-1171/1174-1123/1146-B-F kje/2 q is a number necessary to maintain charge balance with S being sulfur. The catalyst is useful for oxidative coupling of aliphatic and alicyclic hydrocarbon compounds, oxidative coupling of aliphatic and alicyclic hydrocarbon compounds with an aromatic compound to produce higher molecular weight hydrocarbons, and for dehydrogenating hydrocarbon compounds to produce unsaturated aliphatic and alicyclic chains.
